| 中文摘要 | 變形摩擦奈米發電機 (TENG) 在穿戴式裝置和人機介面領域展現出巨大潛力，但有限的輸出功率和摩擦損耗限制了其實際應用。本文，我們提出了一種高效的非束縛碳基非接觸式混合奈米發電機，它結合了摩擦電和電磁 (EM) 感應，將生物力學和環境電磁廢能轉化為可用電能，同時實現自供電非接觸式感測。該發電機使用類石墨粉末捕獲和傳輸摩擦電荷，並使用類石墨紡織品作為摩擦電荷儲存器和可拉伸導體進行電磁感應。值得注意的是，使用再生棉織物作為起始材料，凸顯了永續且環保的材料採購方法。這些協同設計顯著提高了摩擦電輸出功率 (288V，±1.23 μA，4Hz)，並將摩擦電荷保持時間延長至 10,000 分鐘以上，實現了電磁感應起電 (±15V，±2.4 μA，60Hz)。即使在非接觸條件下，輸出在 1 毫米距離處仍能保持 186.5V（摩擦電）和 ±9V（電磁廢料），從而有效地為電子設備供電。據我們所知，這是首次報導的可同時收集兩種能量的非接觸式可拉伸奈米發電機。此外，其性能和摩擦電荷保持時間優於已報告的碳（石墨烯、氧化石墨烯、C60）功能化非接觸式 TENG。最後，展示了一種多路復用自供電非接觸式手勢感應系統。這些進步對於現實世界的應用具有巨大的潛力，例如用於健康監測的節能可穿戴設備、機器人中的非接觸式人機介面以及用於環境監測的可持續自供電感測器，為下一代設備的混合能量收集和感測提供了高效的材料和結構策略。 |
| 英文摘要 | Deformable triboelectric nanogenerators (TENGs) show great promise for wearables and human–machine interfaces, but limited output and friction losses constrain their practical application. Here, we present a highly efficient untethered carbon-based non-contact hybrid nanogenerator that combines triboelectric and electromagnetic (EM) induction to convert biomechanical and ambient EM-waste energy into available electricity while enabling self-powered non-contact sensing. It uses graphite-like powder to capture and transport tribo-charges, and graphite-like textiles as tribo-charge reservoirs and stretchable conductors for EM induction. Notably, the use of recycled cotton fabric as a starting material underscores a sustainable and eco-friendly approach to material sourcing. The synergistic designs significantly enhance triboelectricity output (288 V, ± 1.23 μA, 4 Hz) and extend tribo-charge retention time beyond 10,000 min, achieving EM-induced electrification ( ± 15 V, ± 2.4 μA, 60 Hz). Even in non-contact condition, outputs remain 186.5 V (triboelectricity) and ± 9 V (EM waste) at a 1-mm distance, effectively enabling the powering of electronic devices. To the best of our knowledge, this is the first reported non-contact stretchable nanogenerator that can simultaneously harvest both energy types. Moreover, the performance and tribo-charge retention time are superior to those of reported carbon (graphene, graphene oxide, C60)-functionalized non-contact TENGs. Last, a multiplexing self-powered touchless gesture-sensing system is demonstrated. These advancements hold significant potential for real-world applications, such as energy-efficient wearables for health monitoring, touchless human-machine interfaces in robotics, and sustainable self-powered sensors for environmental monitoring, offering efficient material and structural strategies for hybrid energy harvesting and sensing in next-generation devices. |
